Hexaaquacobalt(II) 2,2′-[naphthalene-1,8-diylbis(oxy)]diacetate dihydrate

Abstract

In the title compound, [Co(H2O)6](C14H10O6)·2H2O, the 2,2′-[naphthalene-1,8-diylbis(­oxy)]diacetate dianion L is not coordinated to the CoII ion. The asymmetric unit contains half of the L dianion, half of a [Co(H2O)6]2+ cation (both molecules being completed by inversion symmetry), and one water mol­ecule. The crystal packing features O—H⋯O hydrogen bonding between the carboxyl­ate groups, the aqua ligands and the hydrate water mol­ecules.
